Description

FIELD OF THE INVENTION
The present invention relates to apparatus for containing contact lenses in a liquid lens care solution. More particularly, the present invention relates to flexible, disposable and transparent apparatus for containing contact lenses in a liquid lens care solution wherein the liquid lens care solution is permanently contained in the apparatus for a one time use. In even greater particularity, the present invention relates to such containing apparatus wherein the contact lenses are contained in compartments separate from the liquid lens care solution, such that the liquid lens care solution is selectively injected into the compartment after the contact lenses are received and hermetically isolated therein.
BACKGROUND OF THE INVENTION
It is commonly known that optical contact lenses must be periodically cleaned and moisturized to facilitate optimum performance when applied to the human cornea. A variety of cleaning and moisturizing solutions are also known. Commonly each contact lens is placed in a separate rigid container wherein a volume of lens care solution has been deposited from a larger separate container of lens care solution. A need exists, however, for a easily portable and disposable lens care apparatus for use by persons who are traveling. When traveling, it can be overly cumbersome to carry the larger volume of lens care solutions and separate lens containers. Also, unexpected overnight stays may leave a contact lens user without solution or containers for caring for his or her contact lenses. This dilemma requires the user to purchase an additional large quantity of cleaning solution and additional containers.
What is needed is a disposable contact lens container having a quantity of lens care solution therein which is maintained in a sterile environment. U.S. Pat. No. 5,054,610 issued to Ajello on Oct. 8, 1991, discloses a disposable single use contact lens conditioning package having a plurality of shallow trays which contain a small quantity of lens care solutions therein. The solution is contained in the trays by a polyurethane film adhesively connect to the trays. To use the lens conditioning package described in U.S. Pat. No. 5,054,610, the film is pulled from the tray and the lenses are placed in the solution for overnight conditioning. Though simple and efficient in its use, the lens conditioning package described in U.S. Pat. No. 5,054,610 requires some dexterity by the user for proper use. The removal of the film from the tray, placement of the contact lenses within the tray and stirring of the contact conditioning solution with the spoon provided can result in inadvertent spillage of the solution and accidental loss of the contact lenses.
SUMMARY OF THE INVENTION
The principal object of the present invention is to provide a disposable, single-use contact lens cleaning and care apparatus that contains the contact lenses and the lens care solution in a hermetically sealed environment.
In support of the principal object, another object of the present invention is to provide a disposable, single-use contact lens cleaning and care apparatus wherein the contact lens care solution is contained in a sterilized hermetically sealed envelope which temporarily isolates the lens care solution until such time that the contact lenses are placed within a containment portion of the invention and are hermetically sealed therein.
Another object of the present invention is to provide a disposable, single-use contact lens cleaning and care apparatus which facilitates a selective combination, subsequent to the placement of the lenses within the containment portion, of two or more chemical agents which an oxidizing agent for disinfecting the contact lenses.
These and other objects and advantages of the present invention are accomplished through the use of a flexible, hermetically sealable envelope having an open end for containing one or more contact lenses. The envelope is divided into one or more lens containing compartments and one or more fluid containing compartments. One or more ports are formed by the envelope to facilitate communication between each of the one or more fluid containing compartments and a selected one or more of the lens containing compartments. One or more flexible balloons, having a quantity of lens care solution contained therein, are encased within the one or more of the fluid containing compartments.
The contact lenses to be cleaned are placed in selected ones of the contact lens containing compartments which are thereafter hermetically sealed by closing a tongue and groove closure defining an upper end of the flexible envelope. After sealing the contact lenses within the envelope, manual pressure is exerted against the selected ones of the one or more balloons to burst the selected balloons and thereby dispense the lens care solution contained therein through the ports and within the lens containing compartments to treat and clean the contact lenses contained therein.
A platinum black catalyst filament is contained in each of the one or more fluid containing compartments to chemically react with the lens care solution to generate oxygen which enhances the cleaning ability of the lens care solution.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to the drawings for a clearer understanding of the invention, it should be noted in FIGS. 1 and 5 that a first embodiment of the present invention contemplates the use of a flexible hermetically sealable envelope 1 constructed of a transparent polyeurethane and having an open end 2. The envelope 1 is divided by a vertical seam 3 formed by heat bonding a first side 4 of the envelope 1 to a second side 6 of the envelope 1. The vertical seam extends perpendicularly from the open end 2 a predetermined distance therefrom. The envelope 1 is further divided by a horizontal seam 7 formed by heat bonding the first side 4 to the second side 6 along a line extending perpendicularly to the vertical seam 3 and therethrough at a point opposite the open end 2.
The envelope 1, and horizontal seam 7 form a lens envelope 5 which is divided by the vertical seam 3 into a right lens containing compartment 8, and a left lens containing compartment 9. The horizontal seam 7 also forms a fluid containing compartment or envelope 11. A plurality of ports 12 are formed by and extend through the horizontal seam 7 to facilitate communication between the fluid containing compartment 11 and the right and left lens containing compartments 8 and 9, respectively.
A transparent hermetically sealed polyeurothane balloon 13 containing a lens care solution 14 is contained within the fluid containing compartment 11. The transparent polyeurothane forming the envelope 1 and balloon 13 accommodate sterilization of the lens care solution 14 and the interior of the envelope 1 from sources external of the envelope 1 such as infra-red light and heat transfer sources. The lens care solution 14 can be any of the cleaning, moisturizing or other lens treatment solutions commonly sold on the market including but not limited to sterile water, hydrogen peroxide, saline or buffered isotonic solutions containing sodium chloride, sodium biphosphate, sodium phosphate or benzalkonium chloride. A flexible tongue and groove closure 16 is connected to the open end 2 for selectively opening and hermetically sealing the envelope 1.
In operation, a right contact lens 17 is placed in the right contact lens containing compartment 8. A left contact lens 18 is placed in the left contact containing compartment 9. Right and left indicia 19 and 21, respectively, are formed on the envelope 1 to distinguish the left and right lens containing compartments 8 and 9.
After the right and left contact lenses 17 and 18 are placed in the right and left contact lens containing compartments 8 and 9, respectively, the tongue and groove closure is closed to hermetically seal the contact lenses 17 and 18 within the envelope 1. Manual pressure is applied inwardly to the envelope 1 proximate the balloon 13 until the balloon 13 bursts. The lens solution 14 is thereby released from the balloon 13, dispersed within the fluid containing compartment 11, through the ports 12, into the right and left lens containing compartments 8 and 9, and in contact with the right and left contact lenses 17 and 18. This process is further assisted by turning the lens containing compartments 8 and 9 below the fluid containing compartment 11 such that the lens care solution 14 will gravitate within the lens containing compartments 8 and 9.
To remove the contact lenses 17 and 18 after cleaning, the envelope 1 is turned to an upright position such that the lens care solution 14 will gravitate within the fluid containing compartment 11. The tongue and groove closure 16 is opened and the contact lenses 17 and 18 are removed from the envelope 1. The tongue and groove closure 16 is then closed to contain the used lens care solution 14 for easy disposal.
A second embodiment of the present invention is shown in FIGS. 2 and 6 and includes every component previously described in the first embodiment. In addition, the second embodiment of the present invention includes at least one reactive filament 19 preferably composed of a platinum black catalyst client to fill in interaction of platinum black catalyst with selected cleaning solution elements!. When the balloon 13 is burst, the lens care solution 14 will contact the reactive filament 19 and react therewith forming an oxidized emulsion prior to passage of the lens care solution 14 within the lens containing compartments 8 and 9 and in contact with the contact lenses 17 and 18 contained therein.
A third embodiment of the present invention is shown in FIGS. 3 and 4 and includes every component previously described in the first embodiment. In addition, the third embodiment of the present invention includes a screen 21 connected to said envelope 1 within the fluid containing compartment 11 and adjacent to the ports 12 for preventing debris (not shown), having a predetermined minimal granular size, from passing from the fluid containing compartment 11 through ports 12 to the lens containing compartments 8 and 9. A granular reactive agent 22, preferably platinum black catalyst, is connected to the screen 21 on a side thereof opposite the ports 12, such that dispersal of the lens care solution 14 from the balloon 13 will contact the reactive agent prior to passing through the ports 12 and into the lens containing compartments 8 and 9. By dispersing the reactive agent 22 along the screen 21, the reactive agent 22 presents a maximum contact surface which is maintained in close proximity to the ports 12 to insure contact between the reactive agent and a maximum volume percentage of the lens care solution 14. The screen 21 also contains the granular reactive agent 22 within the fluid containing compartment 11. From the foregoing, it should be clear that the present apparatus represents a substantial improvement over the prior art.
While I have shown my invention in several forms, it will be obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit thereof.
